I, or should I say... my wife... has a 40B that's s-l-o-w-l-y turning into a mixed reef. So far it only has a couple of colonies (each) of anthelia and xenia, red shrooms, green and red pocillopora, button palys, orange digitata, pink tip torch, a very small red monti cap, and a tiny (accidently broke a chip off of my colony) mint pavona frag. Will be adding more as the colonies in my 125 mature enough to harvest a few frags...
